Topological universality of on-demand ride-sharing efficiency — •Nora Molkenthin, Malte Schröder, and Marc Timme — Chair for Network Dynamics, Institute for Theoretical Physics and Center for Advancing Electronics Dresden (cfaed), Technical University of Dresden, 01069 Dresden

Ride-sharing has been suggested as a solution to a wide range of challenges in personal transportation, ranging from avoiding traffic jams and pollution in cities to improving the availability of public transport in rural areas. However, the dynamics and scaling of such systems are not yet fully understood and definitions of efficiency of ride-sharing are often conflated with the demand. Here we introduce a demand-independent efficiency measure and use it to evaluate the scaling of the efficiency of ride-sharing with the number of buses for different street network topologies. We find and explain universal behaviour of efficiency with vehicle number.
